Description

Technical Field

[0001] This utility model relates to the field of machining, and in particular to a milling and drilling fixture for irregularly shaped nylon sheet workpieces. Background Technology

[0002] The following is a list of available information. Figure 4 The product shown is made of nylon material. It is made by clamping a nylon sheet with a thickness greater than the product design thickness on a CNC machine tool using a vacuum chuck and processing multiple parts at once. The cutting depth during processing is less than the thickness of the nylon sheet, but greater than the design thickness of the product. After the CNC machine tool is completed, the product is cut into shape using an edge trimming machine, and then milled to make the product thickness to the set thickness. Finally, drilling is performed.

[0003] In existing technologies, both milling and drilling can be performed on a milling and drilling machine. Specifically, a vacuum chuck is mounted on the worktable of the milling and drilling machine, and the workpiece is adsorbed onto the vacuum chuck for milling to achieve the designed thickness. Then, a vise is mounted on the milling and drilling machine, and the workpiece is clamped in the vise to complete the drilling process. However, because nylon products are relatively soft, thin, and irregularly shaped, clamping them is not only difficult, but directly clamping the workpiece with a vise can also easily scratch the workpiece surface and make it difficult to ensure the workpiece's levelness, thus affecting the drilling quality.

[0004] Therefore, it is necessary to develop a tooling suitable for clamping irregularly shaped thin plates of nylon material on a milling machine for milling and drilling to meet processing requirements. Utility Model Content

The bottom plane of the clamping body 1 is provided with a boss 1.1 for clamping onto a flat-jaw vise 20, and its upper surface is provided with a first groove 1.2 that matches the shape of the workpiece 10. The depth of the first groove 1.2 is not greater than the design thickness of the workpiece 10 to ensure that the milling cutter will not cut into the clamping body when milling the workpiece. Preferably, the first groove 1.2 is provided with clearance areas 1.2.1 at each corner of the workpiece 10 to facilitate the loading and unloading of the workpiece.

[0029] Furthermore, in this embodiment, the clamp body 1 is cut along its longitudinal direction, dividing the boss 1.1 and the first groove 1.2 of the clamp body into two left and right parts. The bottom of the cut surface of the left clamp body 1a is provided with multiple pins 2, and the bottom of the cut surface of the right clamp body 1b is provided with multiple blind holes 1b.1 that engage with the pins 2. A spring 3 is provided at the bottom of each blind hole. In one embodiment, the pins can be metal rods, and they can be threaded to the left clamp body.
